Nah, I figure once the big battle is done; Harry wants to go back to less interesting cases and more reading time.
He seemed to be doing fine on reading in the first couple of books.
How many books would you say a real dedicated reader gets to read in a lifetime? Maybe, 5,000 to 6,000?
Nope, because a dedicated reader will work a job to buy the books they really want and to, ya' know, have food and a home.
Ahh, but Harry rarely works with finesse; mostly he goes with force.
